This might help someone:

I formatted a spare SD card and loaded NOOBS.

Installed Raspbian Jessie, and ran the : sudo pip install unicornhat --upgrade command

Failed.

Searched on this error message: Python.h: No such file or directory

Ran this command sudo apt-get install python2.7-dev

Re-ran the : sudo pip install unicornhat --upgrade command

Seems OK, yet to be tested fully.
